in java, Write a program which maintains the inventory of an auto dealer. Create a text file of a dealers inventory. The program must read the data into an ArrayList and then maintain it with sales and supplies. We need to create a class of inventory as each line of data will have different types of data. Then we need to create an ArrayList of these objects.

The program should read from a file and store it in a list. It should print the original inventory. I HAVE ATTACHED THE PROGRAMS NEEDED FOR THIS PART WITH A TEXT FILE. YOU SHOULD ADD THE REST. You should ask the user what he/she wants to do:

1. Print the inventory

2.Make a sale

3. Add the new supplies

4. Whenever a purchaser buys a car, it should print the total cost. I HAVE ADDED A METHOD IN THE INVENTORY CLASS.

This code is partly done but i need help finishing it.

( please do as simple as possible using the rest of my code, and explain with comments so that i may understand as much as possible. we are only on chapter 6. only use IF or CASE statements and not FOR statments nor parrsing please.)
